Title: Automatic low pressure control apparatus for compressors
IPC: F04B49/24
Filed: 1925-05-16
Abstract: 234,803. Chicago Pneumatic Tool Co., (Assignees of Hoffman, L. F.). June 2, 1924, [Convention date]. Regulating compression.-Apparatus for controlling compressors in accordance with the receiver pressure is made sensitive to pressures below its normal range of response by increasing the effective area subject to the receiver pressure. The unloading device shown comprises a member c<10> sliding on a stem c'; normally it is held off a valve of the compressor by a spring c<11>, but a sufficient rise in the receiver pressure causes the air transmitted through pipes d, c<12>, to enter a hollow piston c<8> and depress the member c<10> on to the valve, holding its off its seat, through a plunger c<9>. The apparatus for increasing sensitiveness is shown applied both to the unloader and to the unloading valves D, and comprises casings 3 each containing a diaphragm 7 to which a tube 8 formed with openings 11 is secured. By their use, air entering by the pipe d acts on the whole area of the upper membrane and forces its tube 8 down on a valve d<3>; at a sufficient pressure this valve is opened against its supporting spring d<5> and forced on to its lower seat, the air passing through slots 11, d<8> and the pipe c<12> to the second membrane, the tube of which is forced against the hollow piston c<8>, depressing the member c<10> to lift the compressor valve off its seat. The compressor remains out of action until the receiver pressure falls and allows the valve d<3> to be forced upwards by its spring, the air in the pipe c<12> and the unloader escaping through a vent in the lower part of the casing D. When the compressor is to work at higher pressures the adapters 3 are removed, and the pipes d, c<12> connected directly to the unloading valve and the unloader. The automatic operation of the unloader and unloading valve may be suspended, and they may then be actuated by hand by cams 14 rotated by handles 12 and acting through pin plungers 15 upon the diaphragms.

Title: Improvements in or relating to duplicating and like printing machines
Inventor: BROUGHAM LESLIE ERNEST
IPC: B41L11/08
Filed: 1961-04-13
Abstract: 1,012,329. Printing machines. BLOCK & ANDERSON Ltd. April 2, 1962 [April 13, 1961], No. 13347/61. Headings B6C and B6F. In a duplicating or like printing machine which is coupled by the operator to a power drive to effect one complete printing operation, a mechanism is provided on the sheet-feed table of the machine to print, e.g. batch or serial numbers, on the edges of the sheets and is operated from the power drive prior to the instant when a manually-inserted sheet is gripped and fed into the machine. As shown, the additional printing mechanism comprises hand-set type-wheels 36 carried by the hinged lid 35, Fig. 6, of a casing 33, the base 34 of which is fixed to the feed-table 14 and has an edge 34a constituting a side-lay for the sheets. A spring acting on the lid 35 normally holds the type-wheels out of contact with the sheet, and printing is effected by the action of cam 28, Fig. 5, on a lever 42 engaging a pin 43 on a slide 44 mounted on the lid. The slide 44 can be moved to take the pin 43 out of engagement with the lever 42 and thus render the typewheels 36 inoperative. A shaft 23 carrying the cam 28 is coupled by a one-revolution clutch to a constantly-rotating drive-shaft when a foot pedal 15, Fig. 3, is operated, the shaft 23 making one revolution in a time which is short compared with that required for a cycle of the machine. After the edge of the sheet has been printed, a roller 30 on a disc 29 fixed to the shaft 23 engages a lever 31 which operates the normal machinecontrol lever 17 so as to initiate a cycle of the machine. Ink-ribbon mechanism.-The type-wheels 36 print through an ink-ribbon 38, Figs. 4, 6, which extends from a reel 39 over guides 40 to a reel 41. Both reels are free on a shaft 48 and each carries a ratchet-wheel 49 associated with a pawl lever 50. The two pawl levers 50 are reciprocated by a lever 51, Fig. 5, operated from a cam 27 on the shaft 23 prior to a printing operation, and one or the other of the levers 50 is depressed so as to hold it out of engagement with its ratchet-wheel, by means of a rocker 53 operated by a part 54.

Title: Improvements relating to electrical measuring instruments
IPC: G01R27/02
Filed: 1930-05-01
Abstract: 350,669. Resistance measurements. EVERSHED & VIGNOLES, Ltd., ROLFE, G. B., and PERRY, C. E., Acton Lane Works, Chiswick, London. May 1, 1930, No. 13460. [Class 37.] An instrument of the type having a self-contained generator and a deflecting instrument is provided with a switch having three positions, in which the connections are arranged for insulation tests, Wheatstone bridge tests, and Varley loop tests. The generator has two armatures or armature windings A<1>, A<2> which are connected in parallel, as shown, for bridge and Varley loop tests and in series for insulation resistance tests. The switch S shown is of the rotary barrel type with fixed contacts 1 .. 16. In the position shown, connections are made for the Wheatstone bridge test. The potential coil P, in series with a resistance R, is connected in parallel with the armature windings A<1>, A2. The negative terminal of the generator is connected through contacts 10 .. 13 to the junction D of the ratio arms U, V, the positive terminal being connected through a resistance L and contacts 8, 2 to the junction of the variable arm Wand the resistance to be measured, which is connected between the earth and line terminals E, K. The current coil C is in series with a resistance T, which is short-circuited at contacts 6, 7. One end of the coil C is connected to the frame of the instrument, indicated by dotted lines, and thence by contacts 4, 3 to the junction of the arms U, W, the other end of the coil being connected through contacts 7, 6, 5 to one end of the ratio arm V and the link terminal K. For the Varley loop test the connections are the same, except that the connection between contacts 2, 8 is broken and the contacts 1, 9 are connected, thus connecting the positive generator terminal to a terminal M instead of to the terminal E. The terminal M is connected to a good earth, the line terminal K to the looped line, and the terminal E to the faulty line. For insulation testing contacts 2, 8 remain connected, contacts 11,12 and 15,16 also being connected. This puts the armature windings Al, A2 in series with each other and with the current coil C, resistances T, L and the insulation resistance to be measured, the potential coil P, in series with the resistance R, being connected across the generator terminals. The adjustable resistance W and ratio arms U, V are not effective in this test. The switch S may be of other types, or may consist of a two-way switch with positions for bridge and insulation tests and an auxiliary switch for changing from bridge to Varley loop connection.

In a laser using a concave resonator mirror 4, Fig. 1, provided with a partially-transmitting surface on its internal face 5 and an antireflecting coating on its output face 6, radiation reflected back from the output face towards an He-Ne gas tube 1 and having deleterious effects on the laser operation is spilt out of the system by forming the output face with at least a portion inclined to the optical axis. This portion may be either concave, as shown, or convex, and serves to deflect the unwanted reflected radiation 12, Fig. 2, sufficient for it to be spilt out of the system by repeated total internal reflection between the faces 5 and 6. The mirror 4 is formed into a slightly divergent lens by the concave output face, and this lens in association with a collimating lens 7 forms a beam broadening arrangement for the output radiation.
